Lighting is the one part of a yard that exists only after dark, so a landscape lighting installation in Austin, TX, gets judged on what you see and on what you deliberately do not. 

A good layout lays a low wash across the ground plane, sends a narrow beam up into a canopy, and leaves whole stretches in shadow on purpose. Glare is the giveaway. If you notice the fixture before you notice the tree, the aiming is wrong.
